IMEI Number

*#06# Cells Identity Code (IMEI = International Mobile Equipment Identity) XXXXXX XX XXXXXX X TAC FAC SNR SP TAC = Type Approval Code (first 2 digits = country code of the approval-country ) FAC = Final Assembly Code: (01,02 = AEG) (10,20 Nokia) (40,41,44 Siemens) (30 Ericsson) (50 Bosch) (51 Sony,Siemens,Ericsson) (60 Alcatel) (65 AEG) (70 Sagem) (75 Dancall) (80 Philips) (85 Panasonic) SNR = Serial Nr. SP = Spare (always "0")
Software Version *#0000# shows the software version Signal Processing *3370# - Enchanced full Rate Codec (EFR) activation. It will automatically restart. #3370# - Enchanced full Rate Codec (EFR) deactivation *4720# - Half Rate Codec activation. It will automatically restart. #4720# - Half Rate Codec deactivation Enchanced Full Rate will give you much better sound quality when you enable it. The new Enhanced Full Rate CODEC adopted by GSM uses the ASELP (AlgebraicCode Excitation Linear Prediction) compression technology. This technology allows for much great voice quality in the same number of bits as the older Full Rate CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with Regular Pulse Excitation). Both operate at 13 kilobits.(but you take up more space on the network, so they can charge you more) - Talk-time is reduced with about 5%

Sim Clock Stopping
*#746025625# [*#sim0clock#] Checks if the sim clock can be stopped. Sim clock stop is a kind of stand-by mode which will save battery time. This code doesn't work with software version 4.59. It will tell you if it can be stopped or not.

Warrenty Menu
*#92702689# takes you to a secret menu with 6 choices: [*#war0anty#] 1. Displays Serial Number. 2. Displays the Month and Year of Manufacture (0997). 3. Displays (if there) the date where the phone was purchased (MMYY). 4. Displays the date of the last repairment - if found (0000). 5. Makes you capable of transferring user data if you have the gear for it. 6. Shows how long the phone has been used to talk. This counter is not reset by when you "clear timers" like the counters in the call register.

Ericsson 318 and 338 secrets code

Ericsson 318/338

To view IMEI number *#06#To view Software Version enter -> * <- <- * <- * CLR (Use with Care) The Latest Software Version is under Phone Info. To fine tune sound and clean up any echos, place the 388 into the car kit HF 2600. Then close all windows, engine off and type * # * # 3. The E 388 will fine-tune itself in about a few seconds. To activate operator lock <- * * <- (This locks the phone to one carriers SIM card - Use with lots of care) Press Yes to lock and No to notlock. You can also use the codes below to undo this function. USE AT OWN RISK I have tested the function Lock to SP... At least on the 337 there's a submenu: Enter SPCK-code. There are 5 attempts, which is showed (05 attempts). At final attempt the phone beeps as a warning, 'this is the final try', when entering the menu... Wrong code exits the menu, so you are not stuck in something... When you have tried to enter the code (wrong) all five times, the menu is deactivated, and you'll get: 'Not allowed' when entering <-**<- Accessing the Service Program that is not provided with the 388. 1. Connect the 388 to Cable with RS232/TTL converter. 2. Set Comport to 9600bps, 8 data, 1 stop, no parity. 3. Power ON, wait for "2" and send "0B" to the phone. DO NOT Press ENTER. 4. R should be on screen. 5. Send TEST.BIN. (Send as a binary file) 6. 388 should answer "SP,OK". 7. R should be on screen. DO NOT write or read from the IMEI or SPCK area! If you try that you can send the phone to service at once, because you will automatically write FE or EF to EVERY cell in the EEPROM. In other words, all the calibration values for the radio is overwritten... (NOT good) Some commands in the ServiceProg: eere read from eeprom eewe write eeprom lime xxxx xxxx xxxx xxx Learn imei no. Returns Error. imei - Displays IMEI number To FlashProgram a 388: 1. Connect the 388 to Cable with RS232/TTL converter. 2. Set Comport to 9600bps, 8 data, 1 stop, no parity. 3. Power ON, wait for "2" and send "OB" to the phone. DO NOT Press ENTER. 4. R should be on screen. 5. send pre_xxx.bin to the MS. 6. You should recieve a ">".
7. send "0B" again.
8. R should be on screen
9. send prodload.bin to the MS.
10. recieve ">".
Done, I don't have the above files so please don't ask for them.
Interesting Informating (well I thought so :)
The names on the files, sj.....X45 tells you a couple of things. "sj" stands for Sofia-Jane, thats the internal name for the model and x45 stands for "sub-model". The 388 is called model 4/5. The latest 337 phones is called "cr", like in Cost Reduction. They rebuilt the oscillator from a bought-in to one built up with discrete components and that was cheaper.
Programming Channel Indicator or RBS
To enable, send the following command:
EEWR 3EE 1
Wait for the OK prompt, power off* the phone and disconnect it from the interface cables. Powerup and browse through the menus.
To diasable, send the following command:
EEWR 3EE 0
Clearing Electronic Lock
To clear the electronic lock you have to clear the EEPROM address range 03CF to 03DA by sending the commands:
EEWR 3CF 00
EEWR 3D0 00
EEWR 3D1 00
EEWR 3D2 00
EEWR 3D3 00
EEWR 3D4 00
EEWR 3D5 00
EEWR 3D6 00
EEWR 3D7 00
EEWR 3D8 00
EEWR 3D9 00
EEWR 3DA 00
COOL STUFF TO DO
Set ComPort to 115200bps, 8 data, 1 stop, no parity and watch all the phone commands on the screen and so on. Make a call and see what happens as well as shutting down.
*POWER OFF
You should press the NO button a few times until Shut Down comes up on the screen, when it does press yes and this will shut down the phone properly.

1. This is three different channels things depending on the phone state.



a. When the phone is idle, this shows "Bxxx". "B" stands for "Broadcast channel" (a logic GSM channel)b. When a phonecall is in progress, this shows "Sxxx". S stands for "Stand Alone Dedicated Control Channel" SDCCH for short.
c. When the phoncall in up, this shows "Txxx". "T" Stands for Traffic channel. The "xxx" thing is the channel number, 1-124.
2. This shows Rx Level. The values displayed is from 0 to 63. Rx Level is a indicator on how good your reception is for the moment. 0 is a signal strength of -110dBm. 63 is approx -45 to -50dBm.RXLEV is measured in dBm in such a way that incoming signal equals -110.5+RXLEV so that a RXLEV at 50 equals an incoming signal strenght at -50.5 dBm (plus or minus max deviation 0.5dBm)
3. This shows the output power in dBm.
4. This shows the timeslot used for the moment. You can see it when making a call.
5. This shows Rx Quality. Rx Quality is a measurement of how much error correction is required to the speech. 0 indicates none and as the figure rises you hear more pings and pongs on the speech as large parts of the frame are missing. If you have more RxQ then 5, you are on good way to loose your call. RxQuality reads 0-7.RXQUAL is measured by using a table wereas the biterrorrate or BER is interesting and measured in %
RXQUAL table
0 BER < follows="1,11*TA/2." 5v="External" 0v="Battery" 5v="POWER" 0v="POWER" 0v="normal,+5V="test," 12v="test+flash" sec =" POWER"> * <- <- * <- * To read all programmed texts enter -> * <- <- * <- * ->

To view phone network lock status enter < * * < (wait 3 sec)

To fast dial press phone number pos nr and # (Example: 1 5 #)

To fast dial last number press 0 #

To reset main menu language to english enter * # 0 0 0 0 #

To see battery level while phone is turned off quickly press and release on/off(NO button).

To see Extended menus (on older versions) go to MISSED CALLS, empty directory, press and HOLD right arrow button, choose menu type

To see Extended menus (on newer versions) go to READ, empty directory, press and HOLD left arrow button, choose menu type

To edit phone book Turn on extended menus and choose "EditPh.Bk".
Command set
The following commands are recongnized by the phone.Use 9600 baud, 1 stopbit, 8 data bits, no parity.

ATA Pick up phone during ring
AT+GMI Manufacturer identification
AT+GMO Request model Identification
AT+GMR Request revision Identification
AT+GMM
ATDxxx; Dial number xxx
ATH Hangup phone
AT+CFUN=? Define levels of fuctionality in the order of power consumed
AT+CFUN=0 Switches off the phone
AT+CBC Query battery level

Each command has to be followed by a 0x0A, 0x0D sequence, that is carriage return - line feed. These commands will be ackowledged with an 'OK' prompt. An
incoming call is signalled by the string 'RING' sent by the phone at 9600b in normal mode.

The Service provider (SP) lock is used to lock the cell phone to the
SP's SIM card. Once the cell phone is locked to a specific operator,
if one inserts a SIM card from a different operator the phone will
refuse to accept it! The cell phone will however accept another SIM
card from the same operator.
